Selenium nutritional deficiency impacts not only the immune response but also the viral pathogen itself. Dietary selenium deficiency that causes oxidative stress in the host can alter a viral genome so that a normally benign or mildly pathogenic virus can become highly virulent in the deficient host under oxidative stress, the doctors say.

“Deficiency in selenium also induces not only impairment of host immune system, but also rapid mutation of benign variants of RNA viruses to virulence. Selenium deficiency could not only increase the pathology of an influenza virus infection but also drive changes in genome of coxsackievirus, permitting an a virulent virus to acquire virulence due to genetic mutation. It is because that selenium could assist a group of enzymes that, in concert with vitamin E, work to prevent the formation of free radicals and prevent oxidative damage to cells and tissues.”

Zinc is a dietary trace mineral supporting the development of immune cells of both the innate and adaptive immune system. Zinc deficiency results in dysfunction of humoral and cell‐mediated immunity and increases susceptibility to infectious diseases. Zinc supplements given to zinc‐deficient children reduced measles‐related morbidity and mortality caused by lower respiratory tract infections.

“Increasing the concentration of intracellular zinc with zinc‐ionophores like pyrithione can efficiently impair the replication of a variety of RNA viruses. In addition, the combination of zinc and pyrithione at low concentrations inhibits the replication of SARS coronavirus (SARS‐CoV). Therefore, zinc supplement may have effect not only on COVID‐19‐related symptom like diarrhea and lower respiratory tract infection, but also on COVID‐19 itself.”

Iron is required for both host and pathogen and can impair host immunity, while iron overload can cause oxidative stress to propagate harmful viral mutations. Iron deficiency has been reported as a risk factor for the development of recurrent acute respiratory tract infections.
